Sion FS

Sion FS is a polyester reinforced, white thermoplastic membrane formulated exclusively with DuPont’s Elvaloy® KEE, a unique polymer alloy resin. Designed to perform even in the most hostile environments, Sion FS features exceptional solar reflectivity, as well as chemical, UV, impact and tear resistance.

BENEFITS:

  • Highly reflective white color provides energy savings.
  • Very good chemical resistant.
  • Polyester reinforced to provide excellent puncture and tear resistance.
  • Seams are heat welded.
  • Superior breaking strength.
  • Exceeds the requirements of ASTM D 6754 standard for thermoplastic sheet roofing.


Sion NR Detail Membrane

Sion NR Detail Membrane is a white thermoplastic non-reinforced detail flashing membrane formulated exclusively with DuPont’s Elvaloy® KEE, a unique polymer alloy resin. Designed to for use where greater flexibility in the flashing membrane is required to effectively conform to existing flashing details.

BENEFITS:

  • Highly reflective white color provides energy savings.
  • Very good chemical resistance.
  • Seams are heat welded.
  • Exceeds the requirements of ASTM D 6754 standard for polyvinyl chloride sheet roofing.


Sion RM

Sion RM is a polyester reinforced, fleece backed, high performance, white thermoplastic membrane formulated exclusively with DuPont’s Elvaloy® KEE, a unique polymer alloy resin. Sion RM features excellent impact and tear resistance, superior solar reflectance, exceptional chemical resistance and long term sustainability.

BENEFITS:

  • Highly reflective white color can significantly reduce cooling loads.
  • Very good chemical resistance.
